Discover unparalleled control and precision on every trail with the RockShox BoXXer Ultimate Charger 3.2 D2 fork. Engineered from the ground up for racing excellence, this fork delivers consistent performance that keeps chaos at bay and lets you focus on speed, traction, and smooth steering. Featuring the innovative LinearXL air spring, it replicates a coil-like feel—offering supple response at the top, firm mid-stroke support, and controlled bottom-out with the jounce bumper, ensuring reliable performance throughout even the longest descents.

Exclusive to the Ultimate series, the ButterWagonTech oil-delivery system constantly lubricates the bushings, drastically reducing friction and preserving smoothness for extended service intervals.

Its minimalist high-impact graphics and color options—Electric Red or Ultimate High Gloss Black—add style to substance. Designed to fit 27.5" wheels with 200 mm travel and a 20×110 mm Boost axle, the BoXXer Ultimate Charger 3.2 D2 is the perfect upgrade for serious mountain bikers seeking unmatched suspension performance.
